MEDIACONNEX study propose a new way of connectedness for adolescents after a suicide attempt: it is based on the sending of SMS (or mail or other new media), over a period of 6 months after their suicide attempt (SA), in order to allow them to recourse to the care more easily and so to limit the risk of suicidal recurrence. The MEDIACONNEX study will be a multicenter controlled randomized trial (East of France) and there is a funding from the Hospital. The proposal trial will test the hypothesis that adolescent suicide attempters who are receiving SMS (or mail or other new media) from the unit of care in addition to the usual care will do less SA recurrence, than those who are receiving the usual care.
